UNITED STATES PATENT OFFICE.

OLIVER O. XVALKER AND L. B. ALTAFFER, OF EAST PALESTINE, OHIO.-

HAY-WAGON BRAKE.

Application filed March 18, 1885. (No model.)

To aZZ whom it may concern:

Be it known that we, OLIVER O. \VALKER and L. B. ALTAFFER, of East Palestine, in the county of Golumbiana and State of Ohio, have invented a new and useful Improvement in Hay Wagon Locks, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Our invention relates to a lock designed for use upon hay-wagons,and adapted to lock the wheels, the object being to provide devices of this character which shall be cheap and simple in their construction, strong and durable, and which may be readily operated from the top of the load.

With these ends in view the invention con sists in the improved construction and cornbinations of parts hereinafter fully described, and pointed out in the claim.

In the drawings, Figure l is a perspective view of my invent-ion. Fig. 2 is a side elevation showing the device in dotted lines in a locked position.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in both. the figures, A represents the frame of the wagon-rack, and B the forward end thereof.

At the rear end of the frame is journaled in brackets Z1, secured to the under sides thereof, a rod, 0, having at one end a crank-arm, L, which is connected with a longitudinally-arranged rod, E, running from one end of the frame to the other.

D represents a shaft journaled in bearings e, secured to the under side of the frame, at the forward end thereof, and having its ends bent to form cranks N M, the crank-arm N being connected with the rod E, at the forward end thereof.

July 14,1885.

B represents an arm bent slightly upward at its outer end and pivoted at its other end to the pivoted forward end of the rack-frame.

Pivotally connecting the crank M with the arm B, near the inner end thereof, is an arm, 0, and pivoted to the outer end of the arm B is a rack-bar, A, formed at its inner end with a handle, F.

Secured to one of the standards of the forward end of the frame is a guide, K, in which the inner end of the rack-bar A works.

Extending outwardly from the bar or upright to which the guide K is secured are plates a a, either one of which is adapted to be engaged by the rack-bar A.

The operation is as follows: The load is placed in position upon the rack-frame, and the rack-bar A is pulled inwardlyand engaged with either of the plates a a, thus locking the said bar,the several parts assuming the position shown in dotted lines in Fig. 2.

It will be understood that in the operation of our invention any well-known construction of brake-shoes will be employed.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination, with the rack having the forward end, B, and the crank-shafts c D, connected by the rod E, of the rod 0, pivoted front end of the rack and pivotally connected with rod 0, the toothed bar A, pivoted to rod B, a guide, K, and plates a a, substantially as set forth.
